<p>Hey <span class="user-mention" data-user-id="116122">@simulacrum</span>, <span class="user-mention" data-user-id="126931">@centril</span>, <span class="user-mention" data-user-id="116118">@Matthew Jasper</span> --</p>
<p>when we last talked about migrating away from NLL, I think part of the plan was some kind of "hey! this is coming in 1.40!" sort of blog post. AFAIK this did not happen, right? Seems like something we should work on?</p>

<p>Or did we somehow convince ourselves that we've mitigated all of the concerning cases?</p>

<p>wasn't really feasible before to get less powerful machines as the experiment on that agent would be pretty slow, but now we can get them as they'll just contribute whatever they can to the distributed experiment</p>
